This needs to be moved up the priority list. Every week the list of 'quarantined emails' gets longer by five or ten entries. Imagine the list in a year - over a hundred entries! Re-reading and re-evaluating the same list of senders is NOT value added for Dow.

there is a remove emails from quarantine and it doesnt even work if you refresh they show back up WTH give me a delete all the size of the garbage in this makes it extremely hard to find legitimate emails. ever heard of a needle in a haystack?

If not delete, then at least hide or filter out so you don't have wind up reviewing things more than once. But this really is mandatory from a user perspective, since some of us get 20-50 junk mails a day and sorting through them is tedious.

If MS is concerned about admins losing access to potential sample messages from the quarantine, this could just be an archive function that hides the message from the end user's quarantine view while leaving the messages they want to see in the quarantine.

Until recently, my customers were able to perform this action. I've opened today a case with Microsoft Support. It seems this feature has been removed and this action rely on a compliance administrator from now on.

At some point, I can understand why this was removed, but it shouldn't have been. This should be controlled in some DLP policies, not completely removed.

The only current way to filter this is through PowerShell:
Get-QuarantineMessage | where {$_.Released -match "false"}
will show you only messages not already released.
Then if you decide you want to release the message in PS too you can use the Release-QuarantineMessage cmd

once a email is reviewed and released it should be removed from the list. As we are going thru the bulk and spam folders we should be able to also have a button to push to add those messages we see repeat, and block them in one click. Please take care of this, this would make this tool so much better.

This is actually now available in the Security & Compliance Center, just not Exchange Admin Console. Unfortunately S&C doesn't readily show you where emails have been released to recipients, whereas EAC does, so it's not perfect, but it's better than it was.

It is very difficult to maintain the list of quarantined emails, we have a group of staff monitoring this list and have to visit each email in turn to make sure its been release or not. Other systems we have used remove the email once removed from quarantine.... please make the change.

This feature is absolutely NECESSARY for security reasons. We have had large phishing campaigns where the emails were properly quarantined, but we have NO WAY to prevent users from releasing the malicious e-mails and clicking on them. We are only able to delete messages that have already arrived in users' mailboxes. There is nothing we can do for known-malicious quarantined e-mails.

We've been getting hit by spammers weekly during our migration to O365 from Notes. This would be such a great thing to have so users are not sending themselves a bogus quarantine notification from a real quarantine notification. If I could just select them all and DELETE, it would save us so much time during outbreaks.

Couldn't agree more, if an email is convincing enough (there's plenty that are) users will release them from the quarantine and start clicking on malicious links. Admins at least should be able to remove these type of emails from the quarantine to prevent users releasing them.
